SFR6 - Data Redundancy

ID: SFR6 - Category: Composition - Data Redundancy

Modules that deploy resources or patterns that support data redundancy SHOULD enable this to the highest possible value by default, e.g. RA-GZRS. When a resource or pattern doesn’t provide the ability to specify data redundancy as a simple property, e.g. GRS etc., then the modules MUST provide the ability to enable data redundancy for the resources or pattern via parameters/variables.

For example, a Storage Account module can simply set the sku.name property to Standard_RAGZRS. Whereas a SQL DB or Cosmos DB module will need to expose more properties, via parameters/variables, to allow the specification of the regions to replicate data to as per the consumers requirements.
